So here is how to solve the problem.
Let us analyze it first.
S + A = 70
S + L = 80
L + A = 80
Since S + L is equal to L + A, this would mean that S = A.
So S + A = 70 So A = 70/2 = 35kg
And lastly L. L= 80 -35 = 45kgs.
Therefore, Liam's weight is 45kgs.
Hope this explanation helps.
Let me know if you need more help next time. Have a great day!

What is the answer to this
deff fn [24]
So the first column is if a serving is 36 so all you have to do is divide all the different ingredient amounts by three and that will tell you the answer for the serving of 12 row because 12 * 3 = 36

and for the 24 row just multiply all the numbers you get in the 12 row and that will be the answer cause 12 * 2 = 24 

then what ever numbers you get on the 12 serving column just divide those by 12 and that will tell you how much you get for one serving and that will help you solve for the 60 one and the 300 one all you have to do it times the numbers by 60 and then 300

The factorization of the numbers is obtained as

(a) 36 = 2² x 3²,

(b) 60 = 2² x 3 x 5,

(c) 84 = 2² x 3 x 7,

(d) 99 = 3² x 11 and

(d) 180 = 2² x 3² x 5

<h3>Factor of the numbers</h3>

To factorize the numbers we use their factors as show below;

<h3>Factors of 36</h3>

36 = 2² x 3²

<h3>Factors of 60</h3>

60 = 2² x 3 x 5

<h3>Factors of 84</h3>

84 = 2² x 3 x 7

<h3>Factors of 99</h3>

99 = 3² x 11

<h3>Factors of 180</h3>

180 = 2² x 3² x 5

Thus, the factorization of the numbers is obtained as 36 = 2² x 3², 60 = 2² x 3 x 5, 84 = 2² x 3 x 7, 99 = 3² x 11 and 180 = 2² x 3² x 5.

PLEASEEEEEEEE HELP
Rama09 [41]

Answer:

Using the point-slope form:

The equation of the line is given by:

y-y_1 =m(x-x_1) .....[1]  where

m is the slope of the line and (x_1, y_1) is the point on the line.

As per the statement:

Given: Two points i,e (34, 76) and (42, 91)

First calculate slope(m):

Slope is given by:

\text{Slope} = \frac{y_2-y_1}{x_2-x_1}

Substitute the given values we have;

\text{Slope (m)} = \frac{91-76}{42-34}=\frac{15}{8}=1.875

Now, substitute the value of m and (34, 76) in [1] we have;

y-76 =1.875(x-34)

Using distributive property: a \cdot (b+c) = a\cdot b+ a\cdot c

y-76 =1.875x-63.75

Add 76 to both sides we get;

y=1.875x+76

Therefore, the equation of the trend line is: y=1.875x+76

Please help me ???? i don't remember if i should round up or down
Tpy6a [65]

Here is a saying 5 and above give it a shove (round up) 4 and below go down low (round down). In your case you would leave it the same, because when rounding you would round to the nearest 10th.

Example:

54 would round down to 50 and 55 would be rounded up to 60.
